Wielechowski said he thought marijuana should have been removed from the state’s list of controlled substances, and tried to amend the bill to make that change. That amendment failed.

Other amendments to the bill were also defeated during lengthy floor debate Monday, including one from Fairbanks Republican Sen. Pete Kelly that would have made marijuana concentrates illegal in two years.

That failed, with two Democrats joining four Republican majority members in support. One of the Democrats is part of the majority caucus.

Those opposing the amendment said it didn’t appear to match the will of the voters. The initiative that passed in November included concentrates in the definition of marijuana, and those opposing the amendment said they thought banning them would not meet the intent of the initiative.
